Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain the pipe organ, relay how it makes sound, its parts and its types from music sources, describe the divisions and types its aliases name, and distinguish it from electronic organs and other keyboard instruments.

A large keyboard musical instrument that makes sound by driving pressurised air through sets of pipes, each pipe sounding one pitch, with the pipes grouped into stops that the player selects; the registry aliases name divisions and types such as the ruckpositiv, chamber organ and theatre organ. The pipe organ is played from one or more keyboards and a pedalboard, and it is often built into a building such as a church or concert hall.

What it is for: Producing music by sending air through pipes.

It can be explain how it works; relay its parts and stops; describe types and divisions; distinguish it from electronic organs.
